VALVED CLOSURE FOR LIQUID CONTAINERS File Oct. 16, 1930 gwwmtoz J1 "(Pi var Patented Jan 5, 1932 ALMOND w. rrrnnror NEWPORT, MAINE V VALVE]: CLOSURE r03 LIQUID CONTAINERS Application filed: October 16, Serial No. 489,166.

This invention relates to oil stoves or ranges of that type embodying a reservoir from which the oilflows to the burners, and an oil container which is in the form of a large bottle and is arranged in an inverted position on and discharges into the reservoir.

The invention relates more particularly to the :oil container, and has for one of its objects to provide for a container of this charm acter a closure which will prevent the oil from spilling while applying the container to the reservoir and which will automatically open on the application of the container to the reservoir so as to permit the oil to flow therefrom to the reservoir.

The invention has for a further object to provide a closure of the character stated which shall be adapted to permit the oil to flow from the container to the reservoir without noise and which shall be adapted to prevent any foreign matter in the oil from flowing from the container to the reservoir.

The invention has for a further object to provide a closure of the character stated 5 which shall be adapted to prevent oil from dripping from the container while it is being removed from the reservoir.

The invention has for a still further object to provide a closure of the character stated which shall be simple, durable and highly eflicient, which may be manufactured and sold at a comparatively low cost, and which may be readily applied to the container.

The invention is hereinafter fully described and claimed, and illustrated in the accompanying drawing, wherein i v Figure l is a view in side elevation of an oil stove or range reservoir and container of which the latter is equipped with a closure constructed in accordance with my invention.

Figure 2 is a view in side elevation of the closure, and p 5 Figure 3 is a sectional view taken on the vertical plane indicated by the line 33 of Figure 1.

Referring in detail to the drawing, 1 designates the reservoir and 2 the container of an oil stove or range. The reservoir 1 is secured'to the pedestal 3 of a stand, and is connected by a pipe 4 to the burners, not shown, of the stove or range. The container 2'is in the form of "a large bottle, and is arranged in an inverted position on the reservoir 1 with the lower end of its neck 5 extending into the reservoir. The container 2 is supported from thepedestal 3 by a clamp 6. The oil flows from the container 2 into the reservoir 1, and flows from the reservoir by means of the pipe at to the burners of the stove or range. As these parts are of well-known construction, a further description thereof is deemed unnecessary.

' The container 2 is provided with a closure 7 which comprises a cap 8 which is applied to the discharge end of the neck 5. 'The annular wall 8a of the cap 8 is provided with screw threads 9 which engage screwthreads 10 on the neck 5' to removably secure the cap in applied position. The circular wall 86 of the cap18 is provided with an axial opening 11 through which extends a tube 12. The outer portion 1200 of the tube 12 is smaller in external diameter than the inner portion 12?) thereof, and said'outer portion has a snug fit in theiopening 11. A shoulder '13 formed at the juncture of the tube portions 12a and 12?) contacts with the inner surface of the cap wall 86. The inner end of the tube 12 is 3 formed to provide a conical seat 14 for a conical'valve 15,, and the tube is provided near its outer end with radial ports 16.

. The valve 15 is carried by the inner end of a stem 17 which is longer than and extends throughthetube 12. The stem 17 is smaller diametrically than thecoresponding inner dimensionsof the tube 12, so as to permit the oil of the container 2 to flow through the tube 12 when the valve 15 isunseated. The stem 17 is provided at its outer endwith a reduced 7 extension or'stud 18 andmounted upon the studjand secured thereto by a pin19 is a circular head20 which is larger diametrically than the corresponding external dimension of the tube 12. A coil spring 21 which surrounds the outer tube. portion 12aand bears atits inner end against the cap Wall 8?) and at its outer end against the head 20, constantly tends to urge the valve 15 in the direction of its seat 14.

A cylindrical screen 22 surrounds the tube portion 12b and extends inwardly therefrom. The tube 12 may be secured to the cap wall 85 by solder or in any other suitable manner, and this solder or the like 23 may be employed to secure the screen 22 to the tube. The screen 22 surrounds the seat 1 1 and valve 15, and the inner end 24 thereof is of solid formation.

In practice, the container2 is filled with oil, and thereafter the closure 7 is applied to the container. Until the container 2' is applied to the reservoir 1, the spring 21v holds the valve 15 against its seat and in view thereof the oil will not spill from the container during the application of the container to the reservoir. During the application of the container 2, the head 20 contacts with a plug 25 on the bottom wall of the reservoir 1 and moves the stem 17 inwardly against the tension of the spring 21, with the result that the valve 15 is moved inwardly or off of its seat 14, anch thus permittin the oil to flow from the container by way or the passage between the tube 12, and stem 17 and the openings 16 in the tube into the reservoir 1. The screen 22 prevents any foreign matter in the oil from flowing from the container 2 into the reservoir 1. As the valve seat leis located inwardly beyond the cap wall 86, a trap 26 is provided for the foreign matter. The solid inner end 24 of the screen 22 causes the, oil to enter the screen from the sides thereof, and due thereto the oil is divided into such fine streams that its passage from the receptacle 2 to the reservoir 1 will be noiseless. While the receptacle 2 is being lifted from the reservoir 1, the spring 21 will react and move the valve 15 on to its seat 14, with the result that no oil will drip from the receptacle during its removal from the reservoir. As any foreign matter in the oil cannot leave the container 2, the accumulation of carbon on the burners of the stove or range will be reduced to the mini mum.

- While I have described the principle of the invention, together with the structure which I now consider the preferred embodiment thereof, it is to be understood thatthe structure shown is merely illustrative and that such changes may be made when desired, as

ner portion to provide a shoulder bearing against the inner side of said circular wall and secured thereto, the tube being provided at its inner end with a valve seat, a stem extending through the tube and having a diameter less than the internal diameter of the tube, a valve secured to the inner end of the stem, head secured to the outer end of a stem, a coil sprin surrounding the outer tube portion and bearing against the said circular wall and head and constantly urging the valve in the direction of its seat, and a screen secured tothe inner tube portion and surrounding the seat and valve and provided with a solid inner end.

In testimony whereof I hereunto affix my signature. v
